"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"I recently completed an approximately 800 sq. ft. basement renovation with Owens Corning/Lux Renovations, including a full bath and wet bar, and the experience was excellent from start to finish. The project began earlier than expected, stayed on schedule, and was completed beautifully in five uninterrupted weeks. Our project manager, David Guimaraes, was professional and always accessible by phone or text, and onsite weekly, while onsite supervisor Alvaro was present daily and consistently went above and beyond to ensure our satisfaction—including adjusting a wall so a large piece of furniture would fit perfectly. The materials were high quality, and I appreciated the flexibility to substitute my own fixtures, with changes made seamlessly and without issue. I love my basement!!! If you are interested in doing a basement renovation, I would highly recommend this company. Basement renovations are their business and they are great at it. "

"I hired Handy & Some for a bathroom remodel. I received a quote quickly from Sean and he communicated very promptly through the entire process. His price was reasonable and he adjusted it fairly for additions and subtractions that we made. His subcontractors were reliable and everyone was pleasant and considerate while working in the house. Larry, who acted as foreman on the job, was great to work with and always going the extra mile to make sure that everything was done to my satisfaction. Job was completed on schedule and with high quality! Hire them if you have a chance!"

FAQs for basement remodeling projects in Derry, NH

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
